Fig. 10. Diagrammatic longitudinal section of a bud of a Pine. In the 

 axil of all but the lowermost scales (reduced leaves) are buds which 

 develop into dwarf-shoots (bifoliar spurs), each consisting of a few scale-

Fig. 11. Bud of Pine elongating, showing the spiral arrangement of 

 the scales B and L (reduced leaves) each of which, except the lowermost, 

 bears in its axil a bud of a dwarf-shoot ; N foliage leaves of dwarf-shoot ; 

 /Tsmall bud-scales of same ; L leaf-scale in the axil of which it stands. 



The bud of a Pine affords another example somewhat 

 more complex in structure than any yet described (Figs. 

 9, 10 and 11). 



In the first place it has far more numerous scales
